I understand that F=ma, mass is in kilograms and acceleration is metres per second squared so Newtons are just kilograms metres per second squared, but what does that mean? I can’t seem to comprehend it/really understand it intuitively. Why are we adding kilograms, metres per second squared times (or vice-versa)? I understand stuff with division, like density, because it makes sense, like with density, you’re dividing the mass over the volume occupied to see how many kilograms you have per cubic metre of the substance in question, so kg/m^3 , but I seem to have trouble understanding the multiplied quantities, like Newtons.

Basically if you push something 4 kg at 1 m/sec^2 and someone else is pushing something 1 kg at 4m / sec ^2. Then you two are exerting exactly the same strength and if you are pushing each thing over the same distance. Then you two expanded exactly the same energy
